Core Concepts

Nodes & Connectors

Nodes are the individual steps in a workflow. Each node does one thing and passes its output to the next node.

Node Categories

Trigger Nodes

Start a workflow execution. Only one trigger per workflow.

• Webhook — receive HTTP POST/GET requests
• Schedule (Cron) — run on a time schedule
• Email (IMAP) — poll a mailbox
• Event — listen to internal riogentix events
• Manual — trigger from the UI

Action Nodes

Perform operations and produce output data.

• HTTP Request — call any REST or GraphQL API
• Send Email — via SMTP or SendGrid
• Database — read/write to PostgreSQL, MySQL, MongoDB
• File — read/write local or cloud files (S3, GCS)
• Code — run custom JavaScript or Python snippets

AI Nodes

Integrate language models and AI services.

• LLM Prompt — send a prompt to any supported model
• AI Agent (ReAct) — autonomous agent with tool access
• Embeddings — generate vector embeddings
• Vector Store — insert/query from Pinecone, Qdrant, pgvector

Flow Nodes

Control the execution path.

• Switch — conditional routing (if/else)
• Merge — combine multiple branches
• Loop — iterate over arrays
• Wait — pause execution for a duration
• Try/Catch — handle errors gracefully

Transform Nodes

Reshape and enrich data.

• Set — assign/rename fields
• Filter — remove items from arrays
• Aggregate — sum, count, group data
• Parse JSON / XML / CSV
• Date & Time — format, convert, calculate dates

Connecting Nodes

Hover over a node to reveal the output handle (right side). Drag from it to another node's input handle (left side) to create a connection.

• One node can have multiple outputs (parallel branches)
• Multiple nodes can connect into the same input (merge)
• Hold Alt while clicking a connection to delete it

Node Configuration

Click any node to open its Properties Panel:

1. Parameters — inputs specific to this node
2. Settings — retry policy, timeout, notes
3. Output Preview — shows data from the last test run
